Assemblages of miospores and pollen grains found in the upper part of the Suoi Bang Formation in North Vietnam comprise 43 taxa, including two new combinations: Deltoidospora concava (Bolkovitina) comb. nov. and Polypodtites polymicroforatus (Orłowska-Zwolińska) comb. nov. The assemblages from Vietnam largely resemble those from Europe, Iran and Afghanistan; this analogy permitted dating the upper part of the Suoi Bang Formation at the Rhaetian-Lias.

Key words: Miospores, pollen, Upper Triassic, north-west Vietnam.
